Description

Technical Field

[0001] This utility model relates to the field of cooking appliances technology, specifically to an air fryer. Background Technology

[0002] In order to observe the cooking status of food during the cooking process, air fryers in related technologies usually have a viewing window at the top front of the air fryer. However, the placement of the viewing window causes the upper heating element to be placed at the rear, resulting in poor uniformity of the hot air generated by the upper heating element in cooking the food in the inner pot. To solve the above defects, a lower heating element is usually set to assist in cooking food. However, the lower heating element in related technologies usually uses a stainless steel heating tube as the heat source, which has the defects of poor heat penetration and low cooking efficiency. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an air fryer that has the advantages of good heat penetration of the lower heating element and high cooking efficiency for food.

[0005] The air fryer of this utility model embodiment includes a shell and a lower heating assembly. The lower heating assembly includes a transparent cover and a first infrared heating element. The transparent cover is connected to the bottom of the shell. The transparent cover and the shell surround and form a cooking cavity. The first infrared heating element is installed on the side of the transparent cover away from the cooking cavity.

[0006] According to the air fryer of this utility model embodiment, when the temperature of the first infrared heating element of the lower heating component rises, it emits infrared rays. The infrared rays enter the cooking cavity through the transparent cover and achieve effective heating of the inner pot in the cooking cavity in the form of radiative heat transfer. Compared with the stainless steel heating tube in the related technology that achieves heating of the inner pot by conducting heat, the infrared radiation heating of this embodiment has higher heat penetration, and thus higher cooking efficiency for the food in the inner pot.

[0007] Optionally, the air fryer further includes an inner pot that can be installed inside the cooking cavity. The inner pot includes a peripheral wall and a bottom wall, with the bottom wall connected to the lower end of the peripheral wall. The bottom wall is a carbon plate or a transparent plate.

[0008] The air fryer of this embodiment features a bottom wall made of carbon fiber. This carbon fiber, heated by infrared radiation from the first infrared heating element, also emits infrared rays, thus heating the food inside the inner pot through radiation. This results in higher cooking efficiency for the air fryer. Alternatively, by using a transparent bottom wall, the infrared rays emitted by the first infrared heating element can directly enter the inner pot and heat the food there through radiation, further enhancing the cooking efficiency of the air fryer.

[0009] Optionally, the bottom wall is slidably disposed within the peripheral wall along the height direction of the inner pot, the inner wall surface of the peripheral wall is provided with a limiting flange, the inner pot further includes a clamping member, the clamping member is connected to the peripheral wall, the clamping member is spaced apart from the limiting flange in the height direction of the inner pot, and the bottom wall is limited between the limiting flange and the clamping member.

[0010] In this embodiment of the air fryer, when installing the bottom wall, simply slide the bottom wall into the circumferential wall through the opening in the height direction of the inner pot until it abuts against the limiting flange. Then, connect the clamping member to the circumferential wall so that the clamping member presses against the side of the bottom wall away from the limiting flange, thereby achieving a reliable connection between the bottom wall and the circumferential wall. By detachably connecting the bottom wall and the circumferential wall, the material of the circumferential wall can be different from that of the bottom wall; at least part of the circumferential wall can be made of metal or other opaque materials to reflect infrared rays from inside the inner pot, thus better ensuring the cooking efficiency of the air fryer.

[0011] Optionally, the inner pot further includes a sealing ring, and the outer peripheral surface of the bottom wall is provided with an annular groove, part of the sealing ring is fitted in the annular groove, and the remaining part of the sealing ring is pressed against the inner wall surface of the peripheral wall.

[0012] The air fryer of this utility model effectively ensures the sealing of the connection between the bottom wall and the peripheral wall by sandwiching the sealing ring between the inner wall surface of the peripheral wall and the outer peripheral surface of the bottom wall, and effectively prevents the food oil and other liquids in the inner pot from being exposed, thus increasing the difficulty of subsequent cleaning.

[0013] Optionally, a first mounting groove is provided on the side of the bottom wall opposite to the limiting flange, the first mounting groove extending to the outer peripheral surface of the bottom wall, and the clamping member is disposed in the first mounting groove. The clamping member is provided with a threaded hole, and the peripheral wall is provided with a mounting hole. The clamping member is connected to the peripheral wall through a threaded part that passes through the mounting hole and is threadedly engaged with the threaded hole.

[0014] In this embodiment of the air fryer, the first mounting groove conceals the clamping component within it, effectively ensuring the aesthetic appearance of the inner pot. Furthermore, the clamping component is connected to the peripheral wall via a threaded connection, facilitating easy assembly and disassembly between the clamping component and the peripheral wall, and making the installation of the bottom wall onto the peripheral wall convenient and quick.

[0015] Optionally, the peripheral wall includes a first side plate with a through hole, and the inner pot also includes a handle assembly connected to the first side plate, with a first viewing window opposite to the through hole.

[0016] The air fryer of this utility model embodiment has a first viewing window on the handle assembly. Users can observe the cooking status of the food in the inner pot through the first viewing window and the through hole without stopping the air fryer from cooking the food, which effectively ensures the cooking effect of the food and improves the user experience.

[0017] Optionally, the handle assembly includes a mounting bracket, a visible side panel, a visible decorative panel, and a handle. The mounting bracket is connected to the first side panel. The visible side panel is connected between the mounting bracket and the first side panel, and the visible side panel blocks the through hole. The visible decorative panel is connected to the side of the mounting bracket opposite to the visible side panel. The visible decorative panel, the visible side panel, and a portion of the mounting bracket form the first visible window. The handle is connected to the mounting bracket and is partially located on the side of the visible decorative panel opposite to the mounting bracket.

[0018] In this embodiment of the air fryer, the visible side panel seals the through-hole, while the visible decorative panel ensures the aesthetic appearance of the handle assembly and allows users to easily observe the cooking status of the food inside the inner pot through both the decorative panel and the side panel. Simultaneously, the fixing bracket separates the visible side panel and the decorative panel, effectively reducing the heat transfer efficiency between them. This results in a lower temperature for the decorative panel, making it less likely for users to be burned when moving the inner pot by holding the handle.

[0019] Optionally, the air fryer further includes an upper heating assembly mounted on the top of the housing, the upper heating assembly including a second infrared heating element.

[0020] In this embodiment of the air fryer, the upper heating component emits infrared rays through the second infrared heating element, which heats the food through radiation. The upper heating component has higher cooking efficiency. Combined with the first infrared heating element, the food is heated by infrared radiation from both the top and bottom, resulting in more uniform heating.

[0021] Optionally, the top of the housing is provided with a second viewing window, which extends from the outer surface of the housing to the inner top wall of the cooking cavity.

[0022] In this embodiment of the air fryer, the user can also observe the cooking status of the food in the inner pot through the second viewing window. Combined with the first viewing window, the air fryer has a better visual effect and a higher accuracy in observing the food in the inner pot.

[0023] Optionally, the housing includes an inner liner bottom plate, the upper surface of which is provided with a second mounting groove, the transparent cover is fitted into the second mounting groove and connected to the inner liner bottom plate, and the first infrared heating element is connected between the transparent cover and the inner liner bottom plate.

[0024] In this embodiment of the air fryer, the second mounting groove on the inner pot bottom plate and the cooperation between the transparent cover and the second mounting groove ensure that the inner pot bottom plate limits the transparent cover in the horizontal direction. Therefore, after the transparent cover and the inner pot bottom plate are connected, the connection between the two is more reliable and the protection of the first infrared heating element located between them is higher.

[0034] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following is combined with Figures 1-7 This invention describes an air fryer according to an embodiment of the present invention.

[0036] The air fryer of this utility model embodiment includes a shell 1 and a lower heating component 2. The lower heating component 2 includes a transparent cover 22 and a first infrared heating element 21. The transparent cover 22 is connected to the bottom of the shell 1. The transparent cover 22 and the shell 1 surround and form a cooking cavity. The first infrared heating element 21 is installed on the side of the transparent cover 22 away from the cooking cavity.

[0037] According to the air fryer of this utility model embodiment, when the temperature of the first infrared heating element 21 of the lower heating component 2 rises, it emits infrared rays. The infrared rays enter the cooking cavity through the transparent cover 22 and achieve effective heating of the inner pot 3 in the cooking cavity in the form of radiative heat transfer. Compared with the stainless steel heating tube in the related technology that achieves heating of the inner pot 3 by conducting heat, the infrared radiation heating of this embodiment has higher heat penetration, and thus higher cooking efficiency for the food in the inner pot 3.

[0038] It should be noted that the transparent shield 22 is made of transparent glass, and the first infrared heating element 21 is an infrared heating tube made of tungsten wire, carbon fiber or quartz glass. When the transparent shield 22 has a circular plate structure, the first infrared heating element 21 extends along the circumference of the transparent shield 22.

[0039] In some embodiments, such as Figures 5-7 As shown, the air fryer also includes an inner pot 3, which can be installed inside the cooking cavity. The inner pot 3 includes a peripheral wall 31 and a bottom wall 32, with the bottom wall 32 connected to the lower end of the peripheral wall 31. The bottom wall 32 is a carbon plate or a transparent plate.

[0040] By setting the bottom wall 32 as a carbon plate, the carbon plate, after being heated by infrared radiation from the first infrared heating element 21, can also emit infrared rays, thereby heating the food in the inner pot 3 through radiation, making the air fryer more efficient at cooking food. Alternatively, by setting the bottom wall 32 as a transparent plate, the infrared rays emitted by the first infrared heating element 21 can directly enter the inner pot 3 and heat the food in the inner pot 3 through radiation, making the air fryer even more efficient at cooking food.

[0041] Specifically, the cooking cavity has a front opening, and the inner pot 3 is fixed inside the cooking cavity by being pulled out through the front opening. The transparent plate is made of transparent glass, and the inner pot 3 rests against the inner bottom wall 32 of the cooking cavity via the bottom wall 32. In addition, the peripheral wall 31 can be made of metal plate or other materials, and this embodiment is not limited in this regard.

[0042] In some embodiments, such as Figure 6 and Figure 7 As shown, the bottom wall 32 is slidably disposed within the peripheral wall 31 along the height direction of the inner pot 3. The inner wall surface of the peripheral wall 31 is provided with a limiting flange 311. The inner pot 3 also includes a pressing member 33, which is connected to the peripheral wall 31. The pressing member 33 is spaced apart from the limiting flange 311 in the height direction of the inner pot 3. The bottom wall 32 is limited between the limiting flange 311 and the pressing member 33.

[0043] When installing the bottom wall 32, simply slide the bottom wall 32 into the peripheral wall 31 through the opening in the height direction of the inner pot 3 until it abuts against the limiting flange 311. Then, connect the clamping member 33 to the peripheral wall 31 so that the clamping member 33 presses against the side of the bottom wall 32 away from the limiting flange 311, thereby achieving a reliable connection between the bottom wall 32 and the peripheral wall 31. By setting the bottom wall 32 and the peripheral wall 31 to be detachably connected, the material of the peripheral wall 31 can be different from that of the bottom wall 32. At least part of the peripheral wall 31 can be made of metal or other opaque materials to reflect infrared rays from inside the inner pot 3, thus better ensuring the cooking efficiency of the air fryer.

[0044] Specifically, the limiting flange 311 extends circumferentially along the peripheral wall 31 and is connected end to end. The lower surface of the limiting flange 311 is coplanar with the lower surface of the peripheral wall 31. The clamping member 33 is located above the limiting flange 311. After the bottom wall 32 slides into the peripheral wall 31 from top to bottom and abuts against the limiting flange 311, the clamping member 33 is connected to the peripheral wall 31 and presses against the upper surface of the bottom wall 32, thereby limiting the bottom wall 32 in the height direction of the inner pot 3.

[0045] In some embodiments, such as Figure 6 and Figure 7 As shown, the inner pot 3 also includes a sealing ring 35. The outer circumferential surface of the bottom wall 32 is provided with an annular groove 321. Part of the sealing ring 35 is fitted into the annular groove 321, and the remaining part of the sealing ring 35 is pressed against the inner wall surface of the peripheral wall 31.

[0046] By clamping the sealing ring 35 between the inner wall surface of the peripheral wall 31 and the outer peripheral surface of the bottom wall 32, the connection and sealing between the bottom wall 32 and the peripheral wall 31 are effectively guaranteed, and the leakage of food oil and other liquids inside the inner pot 3 is effectively prevented, which would increase the difficulty of subsequent cleaning.

[0047] The sealing ring 35 is preferably made of high-temperature resistant rubber or silicone. The annular groove 321 limits the sealing ring 35 in the height direction of the inner pot 3, thereby ensuring that the sealing ring 35 in the annular groove 321 is effectively prevented from being misaligned during the sliding of the bottom wall 32 in the peripheral wall 31, which would affect the reliability of the connection and sealing between the bottom wall 32 and the peripheral wall 31.

[0048] In some embodiments, a first mounting groove 322 is provided on the side of the bottom wall 32 opposite to the limiting flange 311. The first mounting groove 322 extends to the outer peripheral surface of the bottom wall 32, and a clamping member 33 is disposed in the first mounting groove 322. The clamping member 33 is provided with a threaded hole, and the peripheral wall 31 is provided with a mounting hole. The clamping member 33 is connected to the peripheral wall 31 by a threaded member that passes through the mounting hole and is threadedly engaged with the threaded hole.

[0049] The first mounting groove 322 conceals the clamping member 33 within it, effectively ensuring the aesthetic appearance of the inner pot 3. Furthermore, the clamping member 33 is connected to the peripheral wall 31 via a threaded connection, making it easy to assemble and disassemble the clamping member 33 and the peripheral wall 31, and facilitating the quick and easy installation of the bottom wall 32 onto the peripheral wall 31.

[0050] Specifically, if Figure 6 As shown, after the clamping member 33 is connected to the peripheral wall 31, the upper surface of the clamping member 33 is lower than the upper surface of the bottom wall 32, or is coplanar with the upper surface of the bottom wall 32. Figure 7 As shown, the clamping member 33 includes a clamping block with a cuboid outer contour. One clamping block is sufficient to prevent the bottom wall 32 from moving upwards relative to the peripheral wall 31, thus reducing assembly costs between the bottom wall 32 and the peripheral wall 31. Furthermore, the threaded component is preferably a bolt. The clamping member 33 is located adjacent to the rear plate of the peripheral wall 31. The bolt passes through a mounting hole on the rear plate of the peripheral wall 31 and engages with the threaded hole of the clamping member 33.

[0051] In some embodiments, such as Figure 6 and Figure 7 As shown, the peripheral wall 31 includes a first side plate 312, and the first side plate 312 is provided with a through hole 3121. The inner pot 3 also includes a handle assembly 34, which is connected to the first side plate 312. The handle assembly 34 is provided with a first viewing window opposite to the through hole 3121.

[0052] By setting a first viewing window on the handle assembly 34, the user can observe the cooking status of the food in the inner pot 3 through the first viewing window and the through hole 3121 without stopping the air fryer from cooking the food, effectively ensuring the food cooking effect and improving the user experience.

[0053] Specifically, the first side plate 312 is the front side plate of the peripheral wall 31, and the through hole 3121 is a rectangular hole that passes through the first side plate 312. After the handle assembly 34 is connected to the first side plate 312, it will block the through hole 3121 to effectively ensure the sealing effect of the inner cavity of the inner pot 3.

[0054] In some embodiments, the handle assembly 34 includes a mounting bracket 341, a visible side panel 342, a visible decorative panel 343, and a handle 344. The mounting bracket 341 is connected to a first side panel 312. The visible side panel 342 is connected between the mounting bracket 341 and the first side panel 312, and the visible side panel 342 blocks the through hole 3121. The visible decorative panel 343 is connected to the side of the mounting bracket 341 opposite to the visible side panel 342, and the visible decorative panel 343, the visible side panel 342, and a portion of the mounting bracket 341 constitute a first viewing window. The handle 344 is connected to the mounting bracket 341 and is partially located on the side of the visible decorative panel 343 opposite to the mounting bracket 341.

[0055] The visible side panel 342 blocks the through hole 3121, while the visible decorative panel 343 ensures the aesthetic appearance of the handle assembly 34 and allows users to easily observe the cooking status of the food inside the inner tube through the visible decorative panel 343 and the visible side panel 342. Simultaneously, the fixing bracket 341 separates the visible side panel 342 and the visible decorative panel 343, effectively reducing the heat transfer efficiency between them. This results in a lower temperature for the visible decorative panel 343, making it less likely for users to be burned when moving the inner pot 3 by holding the handle 344.

[0056] Specifically, if Figure 6 and Figure 7 As shown, the visible side panel 342 is made of transparent glass. After the fixing bracket 341 is connected to the first side panel 312, the fixing bracket 341 presses the visible side panel 342 against the outside of the first side panel 312 to block the through hole 3121. The visible decorative panel 343 is made of transparent plastic material. The visible decorative panel 343 covers the outside of the fixing bracket 341 to ensure the aesthetic appearance of the handle assembly 34. The visible decorative panel 343 has a through hole for the handle 344 to pass through.

[0057] In some embodiments, such as Figure 2 As shown, the air fryer also includes an upper heating assembly 4, which is installed on the top of the housing 1. The upper heating assembly 4 includes a second infrared heating element 41.

[0058] That is, the upper heating component 4 emits infrared rays through the second infrared heating element 41, and heats the food by radiation. The upper heating component 4 has higher cooking efficiency for food. Combined with the first infrared heating element 21, the food is heated by infrared radiation from both the top and bottom, and the food is heated more evenly.

[0059] Specifically, if Figure 2As shown, the second infrared heating element 41 is an infrared heating tube made of tungsten wire, carbon fiber or quartz glass. The upper heating assembly 4 also includes a drive motor and a fan. The shaft of the drive motor is coaxially connected to the fan. The fan is located on the side of the second infrared heating element 41 facing the cooking cavity. That is, under the drive of the drive motor, the fan rotates to blow the hot air from the second infrared heating element 41 towards the cooking cavity, so that the upper heating assembly 4 can heat the food simultaneously through heat conduction and radiation. The air fryer has a higher cooking efficiency for food.

[0060] In some embodiments, such as Figures 1-3 As shown, the top of the housing 1 is provided with a second viewing window 12, which extends from the outer surface of the housing 1 to the inner top wall of the cooking cavity.

[0061] Users can also observe the cooking status of the food in the inner pot 3 through the second viewing window 12. Combined with the first viewing window, the air fryer has a better visual effect and the observation accuracy of the food in the inner pot 3 is higher.

[0062] Specifically, the second viewing window 12 extends to the front side of the housing 1 and is located in front of the upper heating assembly 44. The user can simultaneously observe the cooking status of the food in the inner pot 3 through the first viewing window and the second viewing window 12 from the front of the air fryer.

[0063] In some embodiments, the housing 1 includes an inner liner bottom plate 11, the upper surface of the inner liner bottom plate 11 is provided with a second mounting groove 111, a transparent cover 22 is fitted in the second mounting groove 111 and connected to the inner liner bottom plate 11, and a first infrared heating element 21 is connected between the transparent cover 22 and the inner liner bottom plate 11.

[0064] The setting of the second mounting groove 111 on the inner liner bottom plate 11 and the cooperation between the transparent cover 22 and the second mounting groove 111 ensure that the inner liner bottom plate 11 limits the transparent cover 22 in the horizontal direction. As a result, after the transparent cover 22 is connected to the inner liner bottom plate 11, the connection between the two is more reliable and the protection of the first infrared heating element 21 located between the two is higher.

[0065] Specifically, if Figure 4 As shown, the second mounting groove 111 is a circular groove. The housing 1 also includes three fixing brackets 341. The three fixing brackets 341 are fixed to the bottom surface of the second mounting groove 111 by threaded parts. The three fixing brackets 341 are arranged at intervals along the circumference of the transparent cover 22. The fixing brackets 341 are provided with limiting grooves extending along the circumference of the transparent cover 22. The second infrared heating element 41 is inserted into the limiting groove. After the transparent cover 22 is connected to the inner liner bottom plate 11 by three threaded parts, the second infrared heating element 41 abuts against the lower surface of the transparent cover 22.
